Greg,
I'm sorry I can't help you - just wanted to thank you for bringing this trailer to my attention. Was the hitch some sort of universal joint that attached to the seatpost? Very interesting...

I suspect you'll get some energetic feedback.

I don't want to be a misery-guts but 50lbs is a lot of dog, and combined with everything else will make for a heavy - and unstable - load. More than...

Yes, yes, you should put this in one/both of the sticky threads. I almost missed this thread because I usually just visit the stickies.

The bicycle generator shown is 12volts, 0.5Amps (picture 1). It comes out AC but it's more useful as DC, so you use a 'rectifier' which turns the snakey AC signal into a camel-humpy DC signal. The...
